HB-232 Release is imninent! 

The soon-to-be famous HB-232 Scanner/Computer Interface 
continues its development and progress out of Beta and 
into Charlie Testing. All parts are in stock except the 
printed circuit boards which are assured to be right on 
schedule for release by the end of July. The only other 
loose end is the HB-232 Program , but which appears to be 
right on schedule for August 3rd. So if all continues to 
go well, we will start shipping HB-232 Kits on or about 
August 5th. Many of you may have ordered with the 
understanding that shipment might not be before the end 
of August. At this writing, I think we will beat that 
estimate by three weeks. Now THAT is a deal, where in 
this day and age, estimates usually run the other way. 

Speaking of the Charlie Test phase for the HB-232, let me 
take this opportunity to tell you more about it and what 
to expect. You see, the formal announcement of the HB- 
232 won't come until Fall, probably mid-late September. 
Until then, we will continue to refine and develop the 
HB-232 Program and Documentation. This means regular 
changes can be expected, some of which will undoubtedly 
be due to YOUR input. In a way, you Charlie Testers are 
guinea pigs for the formal Release Version to come in the 
Fall. Compensation includes a nice 249! discount off the 
regular price, as well as the formal Release Version of 
the Program and Documentation. You'll have had a hand in 
the development & configuration of the HB-232. Your 
input will be extremely valuable because until now, the 
only other input has been from our persnickety, critical, 
never satisfied Beta Testers. 

Don't get me wrong, these guys have been fantastic and 
indispensable in scraping off the rough edges. But now 
comes another important phase in the development of the 
HB-232: actual market testing. You guys are going to be 
pleased and satisfied with the HB-232 right off, thanks 
to the efforts of the Beta Testers, but we’re depending 
on YOU to help put the polish and the shine on the first 
Release product. You can do this by thoroughly testing 
every aspect of the HB-232 and its Program and then let 
us know what you like and especially what you don't like 
or would like to see changed. The Beta Test crew was 
hand selected for their specialized expertise in critical 
areas of the Big Picture of the HB-232, but you Charlie 
Testers are more typical of the HB-232 Market. 

There is no requirement that you help us out, of course, 
but there will be an incentive for those who provide a 
meaningful report of either a notably positive OR 
negative slant for our study before the end of August, 
1992. At the very least, I will make sure you get at no 

extra cost at least one major revision or update to the 
Program AFTER the Release version, if any are done within 
the year after purchase. Normally, major revisions or 
updates are sold for profit, but yours will be free, if 
downloaded from my BBS, or at a minimal handling charge 
if you prefer a disk. By the way, all registered Charlie 
Testers will receive special clearance to a restricted 
area of my BBS where you'll be able to download Program & 
documentation revisions, special files, & newly developed 
scripts for the HB-232. If you contribute a meaningful 
Report or Evaluation of your impressions of the HB-232 
and its Program before the end of August, you'll receive 
even higher clearance for access to the major rev.ision 
file areas. All original purchasers of the HB-232 before 
September 15, 1992, will be automatically registered as 
Charlie Testers after the first log-in to the Hertzian 
Intercept BBS. Those whose Reports are received before 
Sept 1, 1992, will be upgraded even higher. Purchasers 
of the HB-232 after the formal announcement this Fall 
will not receive special BBS access or entitlements. 

There will be a public message & tech support conference 
established on my BBS for ALL HB-232 Owners, however, and 
I hope to network this conference to a number of BBS’s 
around the USA and Canada to make access easier and less 
expensive. The idea here is that as more and more people 
log onto my BBS, there will be less and less opportunity 
for others to do so A way around this is to network the 
HB-232_C Conference to other BBS's in major areas around 
the continent. It's a simple matter for network-capable 
BBS's to do this, so you might ask your favorite local 
SysOp if he/she would be interested in importing the HB- 
232_C Conference for you. If interested, please refer 
them to me at the Hertzian intercept BBS . [619} 5T8z9247_i 
FidoNet address 202/731 . The more BBS's to participate, 
the more benefit to all. The HB-232 has so much latent 
capability that even we, its developers, don't know all 
the potential impact of this wonderful addition to the 
PRO-2004/5/6 family. You'll see what I mean as you become 
proficient in the use of your HB-232. 

You will wish there were ways to communicate or affiliate 
with other HB-232 Owners, and that's exactly what the 
fledgling HB-232_C conference will be all about! Not 
only will it offer tech support to those who need it, but 
it will be a forum for the exchange of techniques, ideas 
scripts and general info about the HB-232 & its Program. 

I am going to do everything in my power to make this 
Conference widely available on a network of BBS's in key 
areas of the continent to make access easier and long 
distance costs lower. By the way, my standing offer to 
help you find BBS's in your area is still good. Just 
provide me with your Area Code and any other Area Codes 
of interest and I can make you a nice list of BBS's in 
that region for you to explore. 


This is a good opportunity to introduce to you, the 
Feedhorn BBS. [818] 907zlMi > located in the Los Angeles 
area: the first to affiliate with my Hertzian Intercept 
BBS. The Feedhorn's SysOp, Brian Greer, is an avid 
scannist, electronics technician and a most amicable 
fellow. Naturally, the Feedhorn’s theme is radio with 
special emphasis on scanners. If my BBS hours are too 
restrictive for you, or if it's busy when you call, you 
can log onto the Feedhorn BBS and connect with me on two 
different message areas: RAD 10_TEK and/or HB-232_C. 
Of course, there will be other message areas on the 
Feedhorn which are not sent to my Hertzian Intercept and 
vice-versa, but you will find the RAD 10_TEK and HB-232_C 
conferences shared by both BBS's, the contents of which 
are electronically exchanged each night. This means that 
if you post a message to me on the Feedhorn today, I will 
see it first thing the following morning. I’ll fire off 
a reply and you'll see it that very day if you check into 
my Hertzian Intercept, or the following day on the 
FeeAora! This is the concept by which I hope to expand 
the HB-232_C Conference around the continent! All it 
takes is another BBS in your area to cooperate. The only 
disadvantage of the networking concept is the time delay 
since we SysOps exchange our electronic "mail" during the 
wee hours of the night when long distance rates are at a 


FAX call! Either way, the caller won't see a difference. 
Now, if you want to save time with an important written 
message, just prepare a FAX transmittal and send it per 
your customary procedure to (619) 578-9247 anytime EXCEPT 
between 1:3fpat-5:3fpn, PST. Why not send us a test FAX 
message anyway? For those of you ready to upgrade to 
this fantastic computer communications resource, contact

Voice (714) 693-0808 FAX: (714) 693-0705 
BBS: (714) 693-0762 

You might be glad you did; I am. For you BBS callers, 
relax, nothing has changed except that we can go as fast 
as you now. Or as slow. Our modem will match your speed 
whatever it may be.

Developer of ProScsn Frequency Management System 

A lot of ground has been covered in our discussion of 
computerized frequency list management. It's easy to say 
there are many ways to accomplish the task. In my last 
article, I promised an easy solution for non-programmers 
who want to simplify the chore of frequency management. 
ProScan, of course! It's EASY TO USE and costs a lot 
less than most database management programs. What's 
better is not having to learn how to program a database! 

Please pardon my apparent departure from the main theme 
of Scanner Hacking here but this matter of BBS Networking 
is pertinent, because that's the primary channel for the 
timely flow of information in our Hobby! Consider how you 
learn out about scanner hacks? Magazines, newsletters, 
word of mouth, etc.! More often than not, information 
from these media is months old by the time you get it! 
In contrast, I can electronically transmit the entire 
contents of this issue of the tiorld Scanner Report in a 
matter of seconds! Don't get me wrong here; there's no 
substitute for the printed word yet, but by golly, 
neither is there is a substitute for the BBS-1 ink to our 
Hobby! Information about our Hobby can travel around the 
world in a matter of a day or two, and the more of us who 
are linked into this medium, means the more data we can 
pass along, not only to each other but also to those who 
don't own or don't want to use computers!! More and more 
of the data that I am passing to you HERE in the WSR is 
channeled to me by computer link. 


We've just acquired a ZyXEL U-1496E Modem with capability 
of v.32bis/v.42bis and FAX! This means we can match most 
any data transfer speed from 300 to 16,800-baud as well 
as send and receive FAX! The "smarts" are in the modem 
which can detect whether a caller is making a BBS or a 

Before developing ProScan, I looked at custom frequency 
management software in the public domain as well as demo 
versions from the commercial field. I hoped to find a 
ready made solution to eliminate reinventing the wheel. 
Several good programs were available, but none suited my 
particular needs. Too many menus, too many keys to 
press, too many commands to remember, & too many crashes. 

Software development is my profession and scanning is my 
hobby. Since I had the tools to build my own, I decided 
to develop a different approach to frequency management. 

ProScan, in its infancy, was minimal, but served my basic 
needs. It wasn't originally intended for commercial 
distribution, but I passed out copies of ProScan to a few 
scanner friends. At their urging, I improved it and 
released ProScan as a commercial product. 

My primary concern was to keep it simple. I wanted all 
users to be able to learn how to use it in a short time. 
More importantly, I wanted frequency data to be available 
immediately without extra menus and with the fewest 
keystrokes possible (I'd rather press one key than two). 

ProScan is a customized DOS based program which utilizes 
the xBase file format. The main screen offers a view of 
nineteen frequencies at a time. You scroll through the 
frequency list by using the Up/Down, Page Up/Page Down 

The "WORLD SCANNER REPORT" (c) 1991-2; 

V2N7: August, 1992; Page 2 

keys or the Ctrl-Page Up/Ctrl-Page Down keys to go to the 
top and bottom of the file. All data is on-screen with 
exception of notes. Editing a frequency record is as 
simple as pressing the Enter key. Entering of notes is 
only a space bar away. Other on-screen data includes 
automatic bank numbering, channel number, name, class, 
type, call sign and an indicator to let you know if there 
are additional notes. There’s an active clock, screen 
blanking, help screens and more. 

One of the most unique features of ProScan is its ability 
to instantly locate a frequency record, appropriately 
called "Intelligent Seek". When the scanner stops on an 
active frequency, you want the ability to look up the 
channel number and for a quick reference on who's 
talking. With ProScan, you type in the channel number 
and press the Enter key, NO MENUS REQUIRED! You can also 
seek by frequency number or name and you don't have to 
tell ProScan which of the three types it is! When 
looking up names, you can enter in partial strings or the 
first few letters and ProScan will point you to the 
closest match. 

"Intelligent Seek” is especially useful when you get a 
new magazine or book with frequencies lists. You can key 
in "new" frequencies as you read them to see if you have 
them on file (which, if you’ve been scanning long enough, 
you probably do). You don't even have to look at 
ProScan's screen for the results! Three different tones 
are provided depending on whether ProScan finds an exact 
match, close match or no match (the tones can be turned 
off if you're allergic to them). If a single tone 
sounds, you know you already have the frequency on file 
and can immediately check your description against that 
in the publication. If you don't have the frequency, you 
pick a new record location and enter in the new data. If 
you keep the new records grouped together, you can print 
a partial list of just the new frequencies and then enter 
them into your scanner. 

Another great feature is to see your data listed in 
different orders. ProScan allows you to order (sort) 
data by channel, frequency, name, location and type. 
ProScan uses active index files; sorting is not required 
and look ups take a fraction of a second. Indexing 
allows you to change orders immediately without waiting 
for physical sorts to the disk (diskus interruptus ). And 
what's better, you don't need menus for this either. 
Just press the left or right arrow keys to change from 
one order to the next. The results are immediately 
visible on screen. You can also print in any one of 
these orders as well as by selected groups. 

The frequency record structure is simple and somewhat 
universal with particular emphasis on compactness. Each 
record uses only 75 bytes. Many other programs use 
double this amount and more. Conversely, I wanted to 
provide plenty of space for attaching additional notes to 
each frequency. 

Each record is capable of adding approximately 400 lines 

of notes. The note pad offers automatic insertion of a 
time/date stamp each time an entry is made to notes and 
can be turned on or off. The note pad has additional 
functions including string search, search and replace, 
block functions and other word processing features. 

Many long hours went into the development of ProScan. It 
has been thoroughly tested and provides error trapping 
for most events. There are numerous dialogue boxes to 
assist the user when entering data or using the various 
functions. It is these type of features that really make 
the difference. 

ProScan sells for $39.95. For subscribers to the 

venerable WSR, if you order by September 1st, you may 
purchase ProScan for only $24.95. And for those who will 
be using the HB-232 Interface, I will include a free 
utility program for converting your ProScan frequency 
file to an HB-232 compatible Autoload file. ProScan 
comes complete with documentation and an easy to use 
installation program. Requires DOS, hard disk, 640K and 
works with Epson/IBM or compatible printers. Send check 
or money order to DataFile, Inc., P.0. Box 20111, Dept. 
WR, St. Louis, MO., 63123. Please be sure to specify 
disk size (3.5" or 5/25") and a reference to the World 
Scanner Report and this article. If you’re a skeptic, 
you can order a demonstration version for $7.50 which is 
applicable towards purchase. (NOTE: If you want the 
ProScan-to-HB-232 file conversion utility, be sure to 
request it. The HB-232 Utility is not available with 
demo orders.) 

In closing, I hope you enjoyed this series of articles. 
If you have any questions or comments, please drop me a 
line. I would enjoy hearing from you. 73's till then! 

EBITCffl’s tSXSUE: I've known Perry for better than a year 
now (fine gentleman), and have had some opportunity to 
play with his PROSCAN. Not a bad little file manager! 
When I first fired it up, I hadn't had my first MSDOS 
computer for more than a week or two, so you can well 
imagine my lack of savvy and proficiency, yet I was 

navigating through PROSCAN like a pro after only a few 

minutes. If you are not a computer & database expert, it 
could very well be that PROSCAN will open a new dimension 
to scanning for you. If you are going to buy the HB-232, 
PROSCAN might smooth over any initial aversion to data¬ 
base management that you might harbor. Mr. Joseph was 
one of the Beta Testers of the HB-232 so some of the 

"look and feel" of the Program is to his credit. Let's 
hear it from YOU now; drop a note to Perry with your 
questions and comments about database management. Thank 
you, Perry, for your excellent introductory series to 

this increasingly important topic. By all means, please 
feel invited to continue the discourse. I think we're 
ready for Databases 102 now! NOTE : I recently procured 
the Grove FCC Database for California! Wow! Am I ever 
GLAD I'm proficient in database management! If tracking 
a few hundred frequencies is a chore for you, imagine 
what 250,000 might be like! PROSCAN could very well be a 
great learning-aid if you're going places in scanning!

From Joanne Haines, CALIF: Some general comments; I am 
glad you speak your mind, even if you have to step on 
some toes, I would rather you be honest and to the point 
than be two-faced and not hurt anyone's feelings in order 
to keep the subscriptions up or what ever. 

In the WSR V2N6, July 1992, "APOLOGIES" I don't think was 
necessary. But it was nice you had the compassion to do 
so and still get your point across. I agree with you on 
this matter 100%. 

At this time I am unable to purchase a computer, and have 
very little knowledge about them as well, so in my case 
even trying to get a used one is very difficult (not only 
money wise but, because of lack of good hard knowledge 
what to look for.) My uses would be for Scanner/SW Log 
keeping, frequency lists, comments, etc., and I'd use it 
with my Digital Data Interpreter from CCS and of course, 
in the future with the HB-232, you are coming out with 
which I think is just great; everyone should have one! I 
will, God willing and the creeks don't rise! 

Anyway, the way it looks, it will be about two years 

before I will be able to even think about getting a 
computer (Darn it!). So at this time the sections (on 
computers) in the WSR are of little use to me. But I am 
keeping them, and hopefully in the future they will be a 
source of pertinent information. 

I get a lot from your MODs in the tISR. This at least 
gives me some options to improve my scanner, even if the 
money is low at home. I think the How To Do Scanner 
Modifications or How To Properly Hack Your Scanner, was 

EVERY ISSUE. I am sure we could all benefit from this. 

Some things I would like to see, if you make a permanent 

section out of it, are: When you're hacking on your 

scanner's circuit board and destroy one of those little 
flat circuit traces, how can you repair it or replace it 

with a make-shift job? What are the proper ways to 
remove, replace, change, add a wire lead to a surface- 
mounted component? 

Also I like your product news and updates. Like when you 
told us to stock up on Radio Shack's 25-cond cable #278- 
776, because they are discontinuing it. I did! Thanks! 

There are times you get a little too technical for me 

where you lose me. But not very often, YOU KEEP 


pain and very hard for you to do! But it is very much 
appreciated!!! -Joanne 

EDJJORlS REPLYj Thank you for the kind words of support 
and encouragement, Joanne. Normally, I would neither 
solicit nor print complimentary remarks because it's not 
ethical to toot one's own horn. I put yours in because 

whenever a larger issue is at stake, it's probably best 
for all Readers to have a look at BOTH sides. Your not 
being computer oriented and still supportive of computer- 
related material is one pertinent side of this issue. 
You make a good case for "foresight" in anticipating the 
day when you WILL have a computer. That's the spirit I 

hope most other computer-less Readers will have. By the 

same token, we’re not going to deal exclusively with 
computers. They're here to stay, though, and now are 
solidly entrenched into RADIO, and we have to keep pace. 

I'm not a great adviser on computers (yet), but my 

experiences might benefit you and others, so let me 

address those concerns. Mark my words when I said I got 
an XT/clone for $100 and a 40-Mb Hard Drive for another 
$100; total investment: $200. Hardly out of range of 
those who can afford a $400 scanner and other supporting 
toys! For now, let me give a rule or two of thumb to go 
by: AVOID, at all costs, even if almost FREE, the 

original IBM PC and PCjr. These are antiques and not 
worth your hard-earned cash. If the price is right, 
there is nothing wrong with the XT/clone models, even 
though these, too, are antiquated now. An XT will nicely 
control your PRO-2004/5/6 via the HB-232 Interface not to 
mention CCS’ Digital Data Interpreter. If you go for an 
XT/clone, I would strongly urge you to settle for no less 
than 640-k of RAM memory; at least one floppy disk drive 
(preferably two), and not less than a 30-Mb Hard Drive. 
It should also have at least one printer port and one 
serial port. It should be equipped with MS-DOS 3.3 or 
higher. At the XT level, I have no preference for color 
or monochrome, especially if you’re controlling radio 
equipment. Understand that XT/clones are not great for 
productivity now, and I do NOT recomend ’em for anything 
except dedicated control of radio and other equipment. 

The best deals on the used market today appear to be the 
AT/clone class, where again I would recomend a minimum 
of 640-k of RAM (1-Mb preferred) along with one or two 
floppy disk drives; a 40-Mb Hard Drive, and preferably a 
VGA or SVGA color monitor. It should also have at least 
two serial ports and a printer port and be configured 
with MS-DOS 3.3 or higher (5.0 is current.) Frankly, 
even the AT/clone class has now become antiquated. It is 
said that the 386SX/16 class is the entry-level MS-DOS 
computer, and indeed, full-blown 386SX systems can be had 
for under $1000. Prices are dropping like flies in a 
poison cloud. In fact, you can hardly find new AT/clones 
anymore. They're disappearing fast. So used ones should 
become almost as affordable as my clunker XT soon. 

Next subject matter: How To Properly Hack Your Scanner 
might be best driven by specific questions for a while, 
since it is hard for me to guess at what people know and 
don't know, but since you asked . 

R EEAL&1M DAMAGED Q1MUI TRAC ES- Inevitably, this 
happens and most of the time, it's no big deal. The 
repair can be tedious, depending on location of the 
trace, so settle in with some patience and the right 
tools and materials and all will be well. When you have 

The "WORLD SCANNER REPORT" (c) 1991-2; 

V2N7: August, 1992; Page 4 

determined the location of a damaged circuit trace, 

follow it off to either side of the break and find two 
good spots where you can insert a sharp tool such as an 
Xacto Knife. Gently scrape the surface lacquer off the 
traces on either side of the break at accessible 

locations. Scrape until the copper shows bright and 
shiny for a length of at least 1/8" to 1/4". Tin your 
soldering pencil (fine tip, please) and then apply a bit 
of fresh solder to the shiny copper traces. Ensure a 
nice little blob of solder on each trace. Then cut a 
tiny wire, preferably a solid, single strand 26-30ga 

insulated wire to fit between the solder blobs on the 

traces. Strip a bit of insulation from each end of the 

wire and tin those stripped ends with solder. Then 

solder one end of the wire to one solder blob and the 

other end to the other solder blob. Job done! 

upon this subject now with more to come later, perhaps. 
If you only need to solder a wire to one end of a surface 
mount component, no sweat: tin your soldering pencil 
tip, and then apply a bit of fresh solder to the desired 
solder pad of the component. In effect, you'll just 

freshen the solder on the pad; nothing more. Then strip 
the end of your wire and tin it with fresh solder. Then 
solder that wire end to the end of the surface mount 
component. Job done. 

REMOVING SURFACE MQML CgtjPMMIS : well, hell, there's no 
good way to do it without a very expensive desoldering 
tool. So, just crush the component with diagonal cutting 
pliers, and then desolder the broken ends from each pad. 
Replacing surface mount devices is easier, if you have 
them, but you' 11 need tweezers and a steady hand to 
position them properly before soldering one end. In most 
cases, surface mount components can be replaced by 
standard components if you pay attention to lead dress 
and positioning of the component. 

SURFACE MQUjlT CHIPS are a real booger-bear sometimes, 
especially the stock memory chips in the PRO-2004/5/6, 
PRO-2022/2021, PR0-3T/34/32, PRO-2026, BC-/60/950XLT, and 
BC-590/600XLT. Shooey! Many pro’s like to just snip 
them out first and then desolder the cut lead ends from 
the pads. This is the safest procedure for the printed 
circuit board, but of course, the chip is about as useful 
as shoulders on a snake after that. If you're a Klutz, 
maybe that's the best way to remove a SM chip. I can't 
stand to destroy anything, though, so I use desoldering 
wick to first absorb all excess solder from each pin/pad. 

I do two or three applications of the wick in brief 
periods. Then I slip a stout hat pin (the kind with a 
"pearl" on one end) under one row of pins and exert a 
gentle upward pressure as I run the soldering pencil down 
the row of pads. This process makes the pins pop free 
kind of like a row of dominoes falling. Repeat the 
process on the other row and put the chip away in a safe 
place. Use desoldering wick to clean up the vacant pads. 
This technique CAN result in damaged pads and traces if 
you're not careful, though. There's a fine line between 
TOO MUCH heat and not enough ; TOO MUCH force and not 

enough. I boogered up a few pads & traces in my earlier 
days, though I can't recollect damaging any in the last 
couple of years. Nowadays, I can pop a 24-pin SMD chip 
slicker than snake snot in less than 5-mins with no 
damage. But I've done a couple hundred in getting that 
good at it. Take your choice of these two methods, but 
in either one, exercise GREAT PATIENCE and don't get 
rattled or hurried. Patience is the KEY in every area of 
scanner hacking! Take your time and be sure of the 
correctness of every step you take! Good questions! 

Here's an off-the-wall note from a disgruntled inquirer 
that I want to share with you for the sake of involved 
principles on both sides: 

FROM P.S. Omaha. NE: "I was a little surprised today to receive 
what I consider a very rude letter from you, an ex-CEO and 
engineer, to me who could be a prospective customer, just because 
I failed to read some of the literature you sent about sending a 
SASE and eitra stamp with any requests. I'm really sorry about 
that. As a retired engineer, I've made mistakes before and I'm 
very sure that I'll make others. Your short reply could have, for 
the same money, answered my questions and then mentioned that I 
should have sent a SASE and extra stamp. I would have placed a 
couple of stamps in the mail to you immediately. I'm sure that my 
original questions were trashed so for now I'll sit back and see 
if you'll take the time to respond. Just in case my questions 
weren't trashed, I have enclosed a SASE and 2 extra stamps. If 
you don't reply, you'll have 3 stamps to use elsewhere. /P.S." 

ED/TOff’S REPLY : Your questions will be answered to the 
best of my ability by private correspondence, but the 
principles will be addressed here. You make a good point 
from your point of view, to be sure. I don't argue your 
perspective. But you need to see the other side of the 
fence before finalizing your judgment. First, our Policy 
of a SASE and extra stamp for personal replies to hobby- 
related and non-business inquiries is based on NEED and 
certainly not profit. I receive anywhere from five to 
twenty hobby inquiries a day, the cost of which can range 
to well over $10 a day, depending. The time to deal with 
each piece of correspondence ranges from ten minutes, 
minimum, to a half-hour or more. Go figure. Before YOU 
retired, could you afford 10-hrs/day for correspondence? 
It can be perceived as rude of you to expect me to drop 
what I am doing; spend my personal funds and time to 
cater to your leisure pursuit. Your inquiry was not 

business related and there was nothing to suggest that 
you were a potential customer. It is a generally 

accepted courtesy to defray costs of reply when asking 
for free information. You failed to render that courtesy 
at the onset; why is it incumbent on me to include your 
inquiry in the stack to be answered when I can hardly 
afford the time to reply to those who are courteous? In 
the past, I would normally put inquiries like yours at 

the bottom of the stack, but the volume of correspondence 

has grown to the point where the bottom is never reached. 
So we now generate form letters in lieu of ignoring such 
inquiries out right, and I rarely see them. There was no 
intended rudeness on our part; it would have been ruder 
to have ignored you. My staff can quickly stuff form 

The "WORLD SCANNER REPORT" (c) 1991-2; 

V2N7: August, 1992; Page 5 


letters into envelopes, but only I can answer technical 
questions. But I challenge you to see HOW MANY replies 
you get from other authors, publishers and people like me 
who have more to do than they can handle. Bets are that 
over half will ignore you and most of the other half will 
take several weeks or months to reply. In closing, 
please consider that in two years, I have well over 3,000 
hobby inquiries on file, every one of which has received 
a reply. At first, I answered all inquiries, regardless; 
but the load increased to where the SASE + 1 Policy had 
to be etched into stone. I don't see every letter 
anymore UNLESS they qualify first, and then require my 
personal attention. I see YOUR point well enough, but am 
kind of powerless to do anything about it. Do YOU see MY 
point and can you do something about it? I hope the 
resolution is self-evident. 

Folks, I brought this matter out before you primarily 
because a preponderance of my correspondence glows with 
compliments and appreciation for what I do. Trouble is, 
is that there is a limit to what I can do and still make 
a living; pay the rent and feed the kids. Tough world, 
but I wanted you to know the score. We're not rude. 


Comes now an ingenious modification from Mark Persson, 
(Mr. Digital) who designed the KeyBoard Memory Block 
Controller (MOD-28) that appeared in Vol-2 of my SCftMMEB 
MODIFICATION HNDBK . The LINKALL is the next evolutionary 
step in making Extended Memory modifications look and act 
as if they were "factory designed and built".

PRO-2004/5/6 scanners that have been modified with the 
6,400-ch Extended Memory MOD-16 in Vol-1 of the Scanner 
Modification Handbook . The LINKALL controls the four 
memory address lines that are otherwise controlled by DIP 
switches or the MOD-28 KMBC circuit that appeared in Vo 1 - 
function but more importantly, it auto-increments the 
Block address to selected Blocks of your choosing! For 
example, if you program the LINKALL to Autoscan only 
Blocks 00, 01 and 02 the following sequence will occur in 
the Autoscan mode of operation: 

As the scanner passes ch-400 at the end of Block 00, the 
LINKALL selects Block 01 and scanning starts at Ch-1. At 
Ch-400 of Block 01, the LINKALL selects Block 02, Ch-1. 
At Ch-400 of Block 02, the LINKALL then cycles back to 
Block 00, Ch-1 to repeat the process. This Block 00-01- 
02 loop will repeat until you stop the Autoscan process. 
Normal scanner functions are not disrupted; the Extended 
Memory acts more as if it came with the scanner!!! 

Programming the LINKALL is EASY and it scans up to the 
full 6,400 channels from 1 to 16 selected Blocks of 
memory, hands off, if desired. LINKALL always scans in 
Block-ascending order. For example, if you program a 
Block 13-07-02-05 loop, Autoscan of the programmed Blocks 
will be: 02-05-07-13-02-05-07-13,.etc, After the module 
is programmed, memory holds the configuration of the 16- 
Blocks to be scanned or ignored. Reprogramming is not 
necessary at power up! The onboard memory battery in the 
scanner preserves the LINKALL' s memory when the scanner 
is off or unplugged. Block ID is visible during operation 
from four T-1 size LED's mounted in the front panel which 
display the binary count sequence. A 5th LED is used in 
the program mode to indicate if a Block is to be selected 
or ignored (On for programmed, off for ignore). The fifth 
LED remains ON in the Autoscan mode and off in the manual 
81 ock increment mode. Three stock Keyboard keys on the 
scanner are used to increment the Block address and for 
selecting the Blocks to be scanned. Two switches are 
mounted on the rear chassis: one resets the Block address 
to Block 00 or the home Block. The other switch is used 
to enter the three operational modes of the LINKALL 
installed, operation is easy and becomes as routine as 
turning the scanner on. The module has 22 wires to be 
hooked up and if you previously installed the KMBC 
function only one more LED need be installed in the front 
panel. The fully assembled LINKALL module is ready for 
installation but does not include the five LED's or the 
two switches, which are available at Radio Shack and 
electronic supply stores. You might even have the parts 
in your junkbox. The unit is powered from the scanner 
and is completely contained inside the radio. 


CB'ers, etc, will take delight in "The Pouch", a tough, 
low priced carrying case for portable radios, cellular 
phones, pagers, scanners and more! "The Pouch" comes in 
a variety of styles & sizes to fit most handheld radios. 
"The Pouches" are made of 1/4"-thick neoprene, bound to 
an attractive skin, essentially scuba suit material, 
designed so it won't fray, let alone come apart, even 
under water. There is an extremely sturdy belt loop on 
the back made of 2" webbing and a restraining strap made 
of the same material, secured on the front with a large 
Velcro tab. It would seem that "The Pouch" can protect a 
radio from damage by moderate shock, scrapes & vibration.

EDITOR'S NOTE: The following , relative to the new PRO-43 
Handheld Scanner from Radio Shack, was passed to me from 
Tim Dowdle who picked it up from around the BBS Networks: 

"I just bought a PRO-43 in an RS store south of downtown 
Los Angeles today. It is very small, about the size of 2 
cigarette packs on top of each other, but a little more 
in depth. It has 200 channels, am/fm switch, 25 channels 
per second SCAN,50 steps/sec on SEARCH. No speed button. 

I tried a 280 MHz-am freq which worked as well as my PRO- 
2006 with the same antenna. The light isn’t worth much. 
The display is across the top; then the speaker; then the 
keypad. The buttons are small about the size of a pencil 
eraser, some are smaller (the only problem I have found) 
otherwise it is just as good as the PRO-37, or better. No 
time to check intermod. Signals come in clear and some 
come in better than my AR1000." 

don't count on it! It does have "triple conversion" to 
eliminate image interference for all practical purposes. 
And it has the Military Aero Band with selectable Mode 
for the required AM. I don't know about AGC which would 
reduce or minimize intermod and overload. Note that the 
PRO-43 does not have 88-108 MHz nor WFM mode. Neither 
are the SEARCH increments selectable like in the PRO- 
2004/5/6, nor is there a Lockout Review. Nothing has 
been said about a "DIRECT SEARCH" function like that in 
the PRO-2004/5/6 and PRO-34/37, but it's a fair bet that 
it's there. There are conflicting reports on the 
manufacturer of the PRO-43, but the most reliable says 
it's GRE-Japan, same maker of the PRO-2004/5/6 & PRO- 
34/37. It's also said that the PRO-43 requires six "AA" 
cells, but which are packaged more compactly than the 
PRO-34/37. Given its apparent profusion of surface-mount 
components and shrink-wrapped design, I doubt if the PRO- 
43 is going to be very modifiable. So the word to the 
wise is that if you want one, be content pretty much with 
what you get; else don't get it. 

The information to follow comes from the PRO-43 Manual:

Bill, please re-post as you see fit. -Tim- 

Thanks for the scoop, Tim! I have since learned a little 
more about the new PRO-43: it is Cellular capable with 
30 KHz Search Steps after a little work, probably on the 
same level as restoring cellular in the PRO-34/37, except 
you have to crush or remove a surface-mount diode instead 
of clipping a lead. The cellular diode, D-4, is located 
on the BOTTOM board of the PRO-43. Crush or remove it to 
restore cellular. Now I hear it said that if you add a 
diode to the empty spots for D-3, you'll gain 54-88 MHz. 
Two people have sworn to this, but you never know, of 
course. In the PRO-34/37, if you did this, you'd lose 
30-54 MHz, so I dunno at this time. I have a Service 
Manual for the PRO-43 on back order from Tandy, but it's 
not been released yet. I'll have more to discuss after a 
thorough review of the manual and perhaps looking inside 
one if I get a chance. 

Right off, the PRO-43 "looks" like a mini PRO-2006, but 

On the whole and in summary, it looks like the PRO-43 is 
a natural evolution of the PRO-34/37 to bring it much 
closer to the legendary PRO-2006 in a hand held package. 

I think one cannot go wrong with this unit, especially at 
the discounted price offered by MaryMac Industries. 
Let's put it this way: if you’ve been lusting after a 
PRO-37, then the PRO-43 will meet your expectations and 
more. If it's a real PRO-2006 in a hand held package 
that you're waiting for, then don't hold your breath; you 
might want to wait another year or two. More later.,. 


Dear Mr. Cheek! I too agree with Mr. Morris that there 
has been too much emphasis focused on computers in the 
WORLD SCANNER REPORT. I bet many readers can't afford a 
computer and those that can may question how worthwhile 
such a purchase would turn out to be. After all, a poll 
once found that 46? of PC users seldom use them. In my 
small town there are not thousands of stations that could 
benefit from computer management. I was glad to see Mr. 
Morris' letter, as it led me to write these few votes. 

Sincerely, Danny Buntin, Stillwater, Oklahoma 

EDITOR 's REPLY; Dear Mr. Buntin.' Hmm, I dunno about 
polls because they're always slanted. But if you have a 
VCR, you're using a computer; if you have any sort of a 
modern scanner, you're using a computer; if you have a 
reasonably late automobile, you're using a computer. 
There might be a dozen other ways you're using computers 
and not realizing it. All we’re doing here is talking 
about using ANOTHER one. Also, I don't agree that "most" 
HSR readers might not be able to afford a PC! For one 
thing, the WSR is not geared to the bargain-basement 
scanner owner. Over 951 of our readers have something in 
the BC-760/950XLT class or higher. These are $200 and up 
and, mind you, I did a lot of the HB~232's developmental 
work on a funky clunker of a 198 4 XT/clone that cost me 
$100 plus another $100 for the 40-Mb hard drive; a lot 

The "WORLD SCANNER REPORT" (c) 1991-2; 

V2N7: August, 1992; Page 7 

less than typical scanner costs these days! I don't mean 
to speak for yon and Mr. Morris, but frankly I think most 
resistance to computers now is based upon fear of the new 
and clinging to "old school” ways of thinking. I respect 
that; hell, it took me almost ten years to overcome my 
fears of MS-DOS and IBM/clones. The bottom line is that 
the I VSR cannot cater to the "old school”, We will include 
something for it, but we must be avant-garde and ever on 
the move toward the leading edge of technology. Let me 
remind you that in the 1960's & 70's, the "old school" 
still clung to vacuum tube technology, me included, like 
stink clings to manure! But solid-state overwhelmingly 
won. Imagine a vacuum tube newsletter trying to survive 
today! History is about to repeat itself... . 73/Bill 

FROM GQRDY OLSON, FARGO, ND: I bought, and enjoyed both 
your SCANNER MODIFICATION HANDBOOKS, and did some mods on 
a Realistic PRO-2010 that I would like to share with you. 
I have also developed an urge (obsession) with the PRO- 
2004/5/6, and plan on buying a 2006 soon. 

PRO-2010 Mods: SPEEDUP: I successfully changed the 4 
MHz crystal in my 2010 to a 6MHz crystal (bought for a 
mere $1.50 at my local Jim-Pak dealer.) The original 
crystal yielded a mere 7-ch/sec (not the advertised 
8/sec) and after the mod, slightly over 12 chan/sec was 
realized. I originally tried a 10 MHz crystal, but the 
scan went into warp speed, and the radio section would 
not work at all. I would guess a crystal cut for 7 or 8 
MHz might work, but could be pushing it. 

Jack Wilks. St. Louis. MO says! A little trick I found 
for the Automatic Tape Recorder Switch (MOD-33) and the 
CTCSS Decoder, MOD-31: You said to hook MOD-33's Q-l 
input to Pin 13 of the NFM chip. That works fine and 
dandy if you don’t have a CTCSS decoder, but I do. See 

below for how to let the ATRS work with or without tones: 

/yioD-JS P£0-Z00^ 

A MAA_J> P/A/ /3 XC-2 2005

v -' /nob-33 

-£> Pin 7 0/sf LN\- 32i 

OF 7S-32P (mod-ii) 

I found that if you remove R-l (47-k) from MOD-33 and 
solder Q-l’s input wire to Pin 7 of the OP AMP (LM324N) 
on the TS32P, the tape will record only when the correct 
tone is present. Since I have my tone decoder in an 
external box that’s connected to the scanner with a 9- 
cond cable and a 9 pin D-Sub connector. I had to devote 
a fifth wire to that pin 7 (but who cares, 4 spare wires 
are left). By the way, this pin 7 rises to 6 or 7 volts 
when the correct tone is present, and is 0 volts with no 
tone, just like Pin 13 on the NFM chip in the scanner. 

FROM BERT BORLAND: Sanford. Texas: Hi Doc: Got some 
tips for you and my fellow WSR Readers.* About MOD-41, 
the speed-up for the BC-200 with the 800 KHz Ceramic 
Resonator: this sped things up, but about half of the LCD 
memory bank display bars would not blink as the bank was 
scanned or if the squelch opened, the display would not 
change to the one bar to show which was active. Only 
upon pushing the manual button would the display reveal 
the bank. My remedy is a 640 KHz Ceramic Resonator, 
DigiKey part UP9946. This still renders a big jump in 
performance with no ill effects. Digi-Key was all you 
had said, Doc; they are professional in every respect and 
fast shippers, which counts for a lot to one who is 
somewhat in the middle of no-where. I found a great 
source for long-play cassettes - Computer Business Svcs, 
Inc., CBS Plaza, Sheridan, IN 46069 , (317)-758-4414 . 
They invite folks to request info about their megabuck 
computer business system and they will include two very 
long-play cassettes for you to listen to. The clear 
stick-on rubber feet from Radio Shack, number 64-2365 are 
great for the keyboard of the 2004. They act like little 
magnifying lenses and give a much better feel. That’s it 
for now, Doc. See ya. 

EVENT COUNTER: I constructed the Event Counter per your 
instructions in MOD-30. I found that in the 2010, pin 13 
of IC 102 (on the RF board) carries the necessary signal 
to trip the counter. I also found a handy connection 
point in the jumper wire (Yellow) that runs from Pin 13 
to Q126. I simply tapped in a 470-k resistor out to a 
jack, connected the rest up as shown in your book, and 
everything worked; the first time even! 

PRO-2004/5/6 IDEA: Regarding selection of memory banks 
for Extended Memory: rather than use DIP switches or 
keyboard mods, I found a 16 pos BCD coded subminiature 
switch that may be useful. It is the channel selector 
switch for a Motorola Sabre portable radio (a walkie- 
talkie), It can be ordered through any local Motorola 
dealer for about $15-20. They can also order (for some 
pocket change) a spiffy knob for the radio, and the 
adhesive-backed bezel showing the 16 positions (this 
bezel is for the entire top of the portable, showing 
volume knob markings, and the switch settings for the 
’’Securenet” feature.) It should be simple to connect the 
BCD coded switch to a BCD-Binary converter (like the 
74LS42?), then hook it right up to the Memory Board, 
This is one of the mods I plan on doing when I get enough 
saved up for a 2006, 

I don’t plan on doing much more with the 2010, but do 
have the manual if someone else has any problems. One 
mod I would be interested in is if the channel spacing 
when searching could be changed from 12,5 KHz in the 380- 
512 MHz range to 30 KHz, or even 15 KHz, so I could 
better use the GRE Superconverter 9001, I am not going 
to get too hung up on this, since MOD-1 on the 2006 I 
plan on buying would take care of the problem. That’s 
about it for now. Oh, and by the way, if any of this 
material is of use to you, feel free to use or reproduce 
it as you see fit. Sincerely, Gordy Olson; Fargo, ND 

EDITOR's COMMENT .* Step-increment, an internal function of 
the CPU, can't be hacked. NOTE: a franchise Radio Shack 
Dealer down in Katy, Texas sells, Realistic scanners for 
PAR BELOW RETAIL COST; and they're honorable folks. Radio 
Shack's standard warranty applies to their merchandise 
and they ship QUICK! Contact MaryMac Industries (ask for 
Bruce) (800) 231-3680. Typical PRO-2006 cost is $329.00 .

By Sgt. Ludicrous, Electronics Bnthusiast 

I recently put together an emergency power supply for my 
PRO-20136 and thought I'd share with y'all what I came up 
with. The basis for it is from the SCANNER MODIFICATION 
HANDBOOK, Vol-1, Ch-2, pp 37-44. Hosfelt Electronics, 
Inc., has a 12v battery charger kit (#80-220) that has a 
regulated output and comes with two 6-volt, 4.2Ah Yuasa 
gel cell batteries wired in series for 12-volts. The Ah 
rating is below the recommended 10Ah, but this is cured 
by adding more cells in parallel. The kit doesn't take 
long to assemble, about an hour, with interruptions (in 
my case, kids). There is no silk-screened layout on the 
component side of the circuit board so attention to parts 
placement is needed. I installed the larger parts first 
instead of the order given in the directions to reduce 
chances of error. The kit comes with what is needed to 
mount the charger on top of the batteries or, as the 
directions state, it can be used remotely. I opted for 
the latter for several reasons, the main one being that 
I'm a hacker and can't leave anything as-is. Using Radio 
Shack's #270-224 enclosure and parts from my stock room, 

I came to what is shown in the drawings on page 9. 

SI, a DPDT, is labeled WALL-BATT, S2, a DPDT center off, 
is labeled AC-OFF-SOLAR, S3, another DPDT, is labeled 
RUN-CHARGE. S4 is an oddball SPDT center off, on one 
direction, momentary on the other direction. The reason 
for this is that I don't want the Voltage Monitor on all 
the time when I'm operating from the battery because it 
eats about 20mA and subtracts operating time from the 
scanner. There are two caveats when switching from WALL 
to BATT: be sure to turn off the scanner, otherwise Fuse 
1 may blow; be sure to ventilate the enclosure since it's 
a heat producing circuit. The Voltage Monitor is tailored 
for my PRO-2006, but can be easily adjusted for other 
things that operate from 12 volts. As few as two LEDs 
and as many as ten can be used. To align the V-Monitor, 


with my PRO-2006, I first charged the gel cells and then 
used them on the receiver until they ran down to the 
point that the scanner ceased to function. I then set Rs 
so that D1 was on. I have since repeated this just to be 
sure of the turn on/off voltages. It was only a couple of 
days before my emergency power supply got its test under 
fire. Apparently a local sect of ultra-militant squirrels 
planned and successfully executed a suicidal act of 
sabotage. One of them, under cover of being a friendly, 
curious squirrel, infiltrated a local power substation 
and disrupted the lives of his enemy. His martyrdom was 
short lived thanks to the crack commando LINEMAN squad 
which restored electricity and foiled their plans to 
commit further mayhem. You should get one of Hosfelt's 
big 112-pg catalogs. Besides kits, they also carry direct 
replacement IC's for Uniden Bearcat scanners, signal 
meters, varactor diodes, and the Sound Level Meter that 
can be used as an ELF monitor (see WSR, V1N6, July ’91) 
for seven bucks less than RadioShack. I just recently got 
the solar panel so I'm unable to tell you much about it 
other than it’s from American Science & Surplus and was 
specifically designed to recharge 12v batteries. Below 
is a list of sources for this project. Happy Hacking!
